I'm also curious to know in what manner John Kerry is more conservative than George Bush.
Well...by old definitions, Kerry was more conservative foreign policy wise, while Bush was certainly liberal in that regard.
One could also say that Kerry had the potential to be more fiscally responsible than Bush, but we can't know.
"Conservative" does not equal "fiscally responsible". Reagan and both Bushes proved this beyond a shadow of a doubt.
"Liberal" does not equal "fiscally irresponsible" as Clinton convincingly proved.
